Bitbox has been working on Life is Feudal for over three years but recently decided that an Indiegogo campaign was needed to further finance the title to the tune of €200,000. "We have reached a point where additional external funding is required for us to complete the development and release our game, and we spent many nights and days weighing our options," the devs wrote on the campaign page.
The project page has a good summary of this ambitious title's selling points, including a 441-square-kilometer seamless world, full terraforming, a rich crafting system, a no-target combat system, and the ability to track and hunt wild animals.
We recently saw a trailer for Life is Feudal showing some of its potential. The game will be free-to-play with an alpha starting soon after the fundraising campaign if the money is raised.
